If the firewall works on a bridged connection, why not the captured 
portal?  I would be very happy to get a captured portal working on a 
bridge.  I can't get m0n0wall to work on my AP's, so I've put it inline 
between my AP's and my network.  It's in bridge mode because I don't 
want to change my network setup.  But I would like to have some type of 
login for the wireless customers.

Is this functionality something that I can buy (IE, pay someone to put 
into m0n0wall)?
